Answer:
Although more offsprings are produced by the process of external fertilization but the process of internal fertilization is more efficient as compared to external fertilization. This is because, in external fertilization, it is more difficult for the sperm to find the egg and fertilize it. Even after fertilization, it might be that the zygote gets eaten up by a predator. There are none such risks in internal fertilization. The zygote is protected during the internal fertilization which makes this process more efficient.

Answer:
Outer Core of Earth
Explanation:
The outer layer of core of earth consists of iron as a major constituent. Due to internal high temperature and low pressure (as compared to the inner core) , the iron in this layer exists as liquid iron. Since the earth is rotating continuously on its axis, the liquid iron is also rotating thereby producing magnetic field. Due to magnetic field , this sphere of earth is known as magnetosphere.

PCR which stands for <em>"Polymerase Chain Reaction"</em> is a molecular biology procedure to quickly multiply a small sample of DNA into millions or billions of DNA copies for studying purposes.
<em>"Unlinked"</em> signifies that the markers are present in 6 various chromosomes, but to amplify those markers we would need <em>(</em><em>12</em><em>)</em> unique primer sequences, due to it is required to have the reverse and forward primers for every marker; thereby the answer is <em>(</em><em>E.</em><em>)</em>
